I agree with all the comments about it being too soon..
yes, it would appear on the surface that weight limits are an issue
but who knows how things are going to develop now that lipos are approved etc
Also, something that i consider when looking at minimum weights..
6 cell tub chassis.. hard to get to 1500gms as chassis weight is an issue
6 cell carbon fibre chassis.. already light, easy to be spot on with the weight but have to add lead etc
Under 6 nimh rules @ 1500 gms, carbon fibre chassis has no specific advantage over a tub chassis. The difference in weight between a carbon vs tub chassis could be as little as 30grams.
If that were dropped to 1400gms, all of a sudden carbon fibre chassis have weight advantage for the fact that tub chassis are almost impossible to get down to a race weight such as this. The difference in weight between the 2 chassis now would be over 100gms which is a huge difference on the track.
I say the spirit of rc would mean that its meant to be fun and competitive with no real advantage for those with extra $$ to spend. If you want this to remain, you need to leave the weight limits around 1500gms. If you want tub chassis to be uncompetitive and discourage low income entry level racers (who are the foundation of rc racing as far as i see) then drop the weight limits to around 1400gms and give every weight advantage back to a more expensive carbon fibre chassis.
As a newcomer, you're not going to hang around long when you realise its going to cost you $1000 to be competitive.
Just my 2 cents
